Excitation Emission Matrix (EEM) spectroscopy can easily identify turmeric due to its high fluorescence and clear, consistent pattern. Another yellow colorant thought to have been traditionally used, [[Amur cork tree|Japanese yellow wood]] or kihada also fluoresces very brightly but they give very distinctive EEM patterns, making it easy to differentiate between the two. Yellow wood has not been detected so far.

Dayflower + Safflower: Purple is achieved by overprinting or mixing a blue and a red colorant. The dominant purple used throughout the Edo period (1603–1868) is composed of dayflower and safflower. Initially, dayflower was printed over safflower as seen on early two to three color prints; by the 1770s onward, these colors were generally found mixed. By varying the proportions of dayflower to safflower, an array of cool to warm purples were achieved. Even after the introduction of Prussian blue in the 1820s, dayflower and safflower continued to be the preferred mixture.

On prints, this purple can appear brown to tan due to fading and/or shifting of dayflower and safflower. Damage from contact with moisture is frequently encountered because of the highly soluble nature of dayflower. When the print is exposed to water, the dayflower can disperse to reveal the safflower whether or not the purple was produced by overprinting or mixing. Also, the appearance of purple can be found altered from contact with moisture introduced during lining. The water content of the adhesive used to line a print can draw the dayflower into the lining paper, which effectively causes it to move from the print's surface towards the back and into the lining paper.
